摘要： A magnetic head increases the magnetic field strength just below a write gap 14 and thereby improves the recording resolution of a medium. To do so, an upper magnetic pole 10 and a lower magnetic pole 12 are disposed facing one another with the write gap 14 in between, with an end surface of the lower magnetic pole 12 being I-shaped and an end surface of the upper magnetic pole being T-shaped due to the upper magnetic pole 10 being formed of a first upper magnetic pole 10a that is disposed facing the lower magnetic pole 12 and is formed in an I shape that is shorter than the lower magnetic pole 12 and a second upper magnetic pole 10b that is joined to the first upper magnetic pole 10a and is formed wider than the first upper magnetic pole 10a.

In particular, an information recording device that includes a recording head, arranged near or to be close to the recording medium, for applying magnetic fields to the small regions when the recording head relatively moves with respect to the recording medium to pass on the small regions of the recording medium, and a recording head controller for controlling the recording head to cause the recording head to apply magnetic fields to the small regions in a free region of the recording medium in a standby state in which at least information is not recorded on the recording medium to uniform the directions of magnetization of the small regions so as to erase the information in the predetermined free region.

摘要： A magnetic head has a lower sub-magnetic pole and an upper sub-magnetic pole disposed to be adjacent to a moving magnetic disk. The lower sub-magnetic pole and the upper sub-magnetic pole are placed adjacent one another with a predetermined interval at an adjacent point to the magnetic disk. A magnetic field is generated between those magnetic poles so that the magnetic disk is magnetized. A soft magnetic film extending between the magnetic poles and a first non-magnetic film and a second non-magnetic film supporting the soft magnetic film are disposed between the magnetic poles.

摘要： A thin film magnetic head comprises a magnetic yoke piece exposed at a medium-opposed surface adjacent a gap layer. A magnetic yoke layer is connected to the magnetic yoke piece at a position retracting from the medium-opposed surface. The tip end of the magnetic yoke layer is exposed at the medium-opposed surface. A non-magnetic layer is interposed between the tip end of the magnetic yoke layer and the magnetic yoke piece at the medium-opposed surface. The non-magnetic layer serves to space the tip end of the magnetic yoke layer away from the other magnetic yoke layer which is separated by the magnetic yoke piece and a gap layer, for example, from the magnetic yoke layer. It is possible to reduce a magnetic field directed to the other magnetic yoke layer from the edges of the magnetic yoke layer protruding in the lateral direction of a data track. Such magnetic fields from the magnetic yoke layer hardly induce magnetic reversal on a magnetic recording medium such as a magnetic recording disk or tape.

摘要： An information processing device includes a central processing unit, a cache memory unit and first and second decision circuits. The first decision circuit identifies one of partitioned address areas to be accessed before the central processing unit accesses the cache memory unit. The second decision circuit determines whether the above one of the partitioned address areas is a cachable area or a non-cachable area before address tag data is referred to in the cache memory unit.

摘要： A liquid resist is introduced between adjacent conductive lines of a coil pattern girdling around a magnetic core piece. When the liquid resist is cured, an insulating resin filler can be fixed between the adjacent conductive lines of the coil pattern. An insulating metallic layer is formed to extend over the insulting resin filler and the conductive lines of the coil pattern. Thereafter, the insulating metallic layer is subjected to a flattening grinding treatment until at least a part of the conductive line is exposed at a flattened surface. Of the resist, of a higher fluidity, penetrates in every hole and corner between the adjacent conductive lines, the gap defined between the adjacent conductive lines is fully filled with the insulating material. No voids remain in the gap. The conductive line of the coil can be reliably prevented from corrosion or oxidation. Moreover, a relatively brittle of fragile insulating resin filler is reliably prevented from being subjected to the flattening.

When the liquid resist is cured, an insulating resin filler can be fixed between the adjacent conductive lines of the coil pattern. An insulating metallic layer is formed to extend over the insulting resin filler and the conductive lines of the coil pattern. Thereafter, the insulating metallic layer is subjected to a flattening grinding treatment until at least a part of the conductive line is exposed at a flattened surface. Since the liquid of the resist, of a higher fluidity, penetrates in every hole and corner between the adjacent conductive lines, the gap defined between the adjacent conductive lines is fully filled with the insulating material. No voids remain in the gap. The conductive line of the coil can be reliably prevented from corrosion or oxidation. Moreover, a relatively brittle of fragile insulating resin filler is reliably prevented from being subjected to the flattening grinding treatment.
摘要翻译：在围绕磁芯片的线圈图案的相邻导线之间引入液体抗蚀剂。当液体抗蚀剂固化时，可以在线圈图案的相邻导电线之间固定绝缘树脂填料。绝缘金属层形成为在绝缘树脂填料和线圈图案的导线上延伸。此后，对绝缘金属层进行平坦化研磨处理，直到导电线的至少一部分在平坦表面露出。由于具有较高流动性的抗蚀剂的液体渗透在相邻导电线之间的每个孔和拐角处，所以相邻导电线之间限定的间隙被绝缘材料完全充满。间隙中没有空隙。可以可靠地防止线圈的导线腐蚀或氧化。此外，可靠地防止相对脆弱的脆性绝缘树脂填料进行平坦化研磨处理。
